SIECIPICATION forming partei Letters Patent No. 329.460, dated November 3, 1885. I application amanti; 11, was: ,sami No. 111.900. momodsii 4 To all whom it may concem:

Be it known that I, HERMANN LEMP,a citi- Y zen of the United States, and a-residcnt o f Hartford, in the county of Hartford and State 'of- Gonnecticut, have invented certain newand useful Improvements in Electric Switches, of which the following is a specification. My invention relates toelectric switches of any kind adapted to makeand break, reverse, or otherwise change or modify electric connections; whereby 4a quick or -snapping action may be obtained in the operation ofthe switch'by skilled or,l unskilled persons. i

My invention consists in the combination, with' the moving portion of the switch by whose movements the changes of connection are eiected, of au, actuator of any desired form', but preferably of the form or construction herein shown, arranged to' engagevwith two oppositely-inclined cams er surfaces connected with or applied'to the movingporton ci the switch, and a lifting device, whereby the. actuator may be brought from engagement vwith the bottom of either incline to engagement with the top' of the other it may by engagement with the cam or incline, throw the switch quickly into a position the reverse of that which said switch occupied before the operation.

My invention consists, fui-ther, in certain improved details of construction and combinations Aof paris that will be described in connection with the accompanying drawings, and

will be then specified in the claims.

In this specication I have described the application of my invention to a switch in' which the moving portion consists of asimple piv'oted lever; but it will be readily underplied to has a rectilinear or sliding moving insteadof a rocking moving, as in thecasesupposed. Iny any case, -no' matter what the form of the switch or the' nature of the' movement given to the movable portion of the switch, all that is necessary in order to embody therein the principles of my present invention is to' applyor connect with such movable portion the two 5o .oppositely-in`clined ways or surfaces with which the actuator engages,

and its object is to provide a meansincline, wherev of a rather stii spiral spring,

,in its simplest form of stood that the invention might be readily vzip-.-

switches when the movable portion .L of the lifter is turned to the right, and

said actuator'being` brought into engagement with either incline by the operation of the lifting device according to the direction of movement desired in the switch.

' In the accompanying drawings I have shown in plan in Figure 1 a simple form of make and break 'switch embodying my invention, themovable portion of theswitch consisting of a simple pivoted lee'r adapted to make and break connection with one or more. contactsprings. Fig.l2 illustrates the application' of the invention to a sliding switch. B indicates the switch-lever or movable portion of the switch, pivoted at E on a suitable base, A, and movable into and out of contact with suitably-mounted springs, CG. The connections are made to` the springs, as indlcated, and the circuitis completed through the lever, which consists of or carries conducting material. Stops K the lever, which, in the position shown, completes the circuit, while in the position shown in dotted lines the circuit is broken.

' D D indicate two oppositely-inclined -ways or cams, placed at opposite sides of the levers fulcrum, and forming the cams or surfaces with which the actuator engages to shift the switch. The actuatoris' shown in the presentcase as consistingof a'spri'ng-actuated block, roller, or'follower, F, secured to the end F, xedto'the determine the movements of base A, ,but might be of other forms or constructions.

The'lifter or device for moving the actuator to engagement with the top of one incline 0r the other, according' to the movement of the switch desired, is indicated at G. It consists alever mounted independently of the switchlever and having the two arms or forks H H, adapted to engage, respectively, with the actuator in the two posi-v tions ofthe switch, The lever G is provided with a suitable operating-handle, L.

In the position of the parts shown the circuit is closed. To shift the switch, lthe handlle t e prong or arm Il of the lift'er raises the block F of the actuator along the incline D and over the divide between the two iuclines, so that'it nto engagezent with the incline 1f), cnt he actuator, beingv unobstructed, wn the incline and at the same time throws the switch-lever in to the po-Y lown indotted liliesr thus rnpturing Lit- The arm or prongll of the lifter Y Y ipositionto engage with the actuator,

operation maybe reversed inobvious by simply turning the handle ofthe Y Y the left.' WSuitable stops areformed,

block or follower Fvfrom becoming 5`iodilication`shown in Fig. 2 'the portion Bof the switch slides so as and break the connection between springs C Y.C 'in obvious-xnannenY In spects v the operation ,is substantially 2 as in. the switch shown inFig. 1. I claimas myinventon A combination, with an electric switch, :tnator therefor, two oppositely -in- Y aylsor cani-'surfaces upon which ,said

may rie, and 'a lifterfor moving thje from citiv inte engagement 2. The combination, with an electric switch, vof a spring-actnator adapted to engage with -either of two oppositelynclinedways or'cams connected to the switch, and a lifter for lifting .the actuator from the bottoni of either. incline over the Ytop thereof to engagementwit-h'the other atY or near its top.
